revision是可数名词还是不可数名词，复数怎么写

可以是可数，也可以是不可数，意思不同的
呵呵
复数直接加s

词典里的：
/rɪˈvɪʒn; rɪ`vɪʒən/ n (a) [U] ~ (for sth) revising or being revised 复查; 校订; 修正; 改正; 复习: Our budget needs drastic revision. 我们的预算需作重大修改. * (Brit) do some revision for the exam/some exam revision 为准备考试而复习. (b) [C] instance of this 复查; 校订; 修正; 改正; 复习: undergo a final revision 经最后修订. (c) [C] thing that has been revised 经修订或改正之物; 修订本; 修订版: submit the revision of a novel for publication 送交小说的修订本准备出版.

意思为校订本; 修订本时，可数，revisions。
如：after four revisions，经过四次修订
